Ok I havent been around for a bit due to family crisis. But I had 2 ce2 tanks die on me, ok. So I made 2 new tanks, both lasted maybe 2 days and died. I have been using only my provari and infinity and been using the 2.4-2.6ohm ce2's and voltage around 4.1v. I have been using these type of ce2's for months and have never had one die on me. I fill the tank maybe twice and clean and reuse and never had an issue. I installed 2 new ones and both died. I dont get it. It dont matter, fat or stranded wicks. any ideas???? Thanks
